2.4 Connection with two engines, one starter battery and one house and one bow battery
Figure 2.4: Anschluss mit zwei Motoren und 1 Starter–Batterie, LM-Strom < 250A
Figure 2.4 shows the installation for yachts with two engines and one starter battery. If the total charging capacity of
the two alternators is less than 250 A, it is possible to work according to chapter 2.3a with parallel connected
connections (-1/+1) and (-2/+2) for the alternators and starters (-4/+4). If the total alternator output is greater than 250
A, proceed according to Figure 2.3b. The installation of the EM-box eliminates the need for a second starter battery
while maintaining the same starting reliability.
